The effect of increased speaking rate on the perception of disordered speech in children with cleft palate was studied. Six children with cleft palate (ages 7 years to 10 years of age) produced three different sentences over a continuum of speaking rates. Fifteen judges rated each sentence according to the severity of disordered speech perceived, including nasality, nasal distortions, nasal emission, glottal stops, and pharyngeal fricatives. Mean ratings for the 15 judges were determined for each sentence. The results indicated that the perception of disordered speech did not increase as a function of increased speaking rate. Possible explanations for the results include: (1) The speakers with cleft palate made adjustments in movement strategy to accommodate the reduced time in a manner similar to speakers without a cleft. (2) The speakers with cleft palate used movement strategies which, although unlike those used by speakers without a cleft, allowed them to avoid speech deterioration. (3) Increasing speaking rate did not reduce the time available to an extent that it was necessary to change movement strategy.
研究了语速加快对腭裂儿童紊乱语音感知的影响。六名腭裂儿童（年龄在7岁至10岁之间）在一系列语速下说出三个不同的句子。15名评判员根据所感知到的紊乱语音的严重程度对每个句子进行评分，包括鼻音、鼻腔变形、鼻腔漏气、声门塞音和咽擦音。确定了15名评判员对每个句子的平均评分。结果表明，紊乱语音的感知并没有随着语速的加快而增加。对结果的可能解释包括：（1）腭裂患者在运动策略上进行了调整，以类似于非腭裂患者的方式适应减少的时间。（2）腭裂患者使用的运动策略虽然与非腭裂患者不同，但使他们能够避免语音恶化。（3）语速加快并没有将可用时间减少到必须改变运动策略的程度。
